This is very correct. I added grub, and then expected a nice linuxy grub
experience, but could not get netbsd to completely boot. It would
print out all the hardware intitialization messages, but then get to a
point where it said "root:" and hang. So I tried to delete grub and get
back to the netbsd bootloader. I tried installboot, fdisk -B, fdisk -i,
etc, reading the man pages and doing the things that seemed, well,
likely to fix things. Somewhere in all of that, I destroyed the mbr. Now
it won't boot at all, and booting to windows showed me that I have no
I used to have two netbsd partitions and one dos partition on disk 0.
Disk 1 is WinXP. When I installed XP, I had disk1 disconnected and disk1
was the primary. I don't think that had much effect on this current

secondary, and I'm using a sector editor to root through the disk. This
